The molecule DMT N,N - is a psychoactive chemical that causes intense visions and can induce its users to quickly enter a completely different environment that some have likened to an alien or parallel universe. The transition from our world to theirs occurs with no cessation of consciousness or quality of awareness. In this environment, beings often appear who interact with the person who is using DMT. The beings appear to inhabit this parallel realm. The DMT experience has the feel of reality in terms of detail and potential for exploration. The creatures encountered are often identified as being alienlike or elflike. Some of the creatures appear to be three-dimensional. Others appear to lack depth.
DMT is also naturally produced in small quantities in the human brain, and it has been hypothesized that DMT is produced in the pineal gland in the brain. The pineal gland appears in the developing human fetus around 49 days after conception.
